Temperature, Time and Pressure

Post  rishi777 on Fri Sep 18, 2009 2:11 am

Very Happy It is commonly assumed that petroleum formation is a function of the increasing burial of the source rock. However, other factors than the burial history; such as the type of originating kerogen, and the geothermal gradient are also important.

"Kerogen" refers to the organic component of source rock. It began as living organisms, became sediments (comparable to top soil), and then, as they were overlaid, began the change from sediment to sedimentary rock (a process known as "diagenesis"). The original organic material, and the microbial activity it contained, influenced the extent and nature of the hydrocarbons which are eventually produced. The first hydrocarbon generated is methane (sometimes called "biogenic gas").

Considerable melting of the continental crust is a likely consequence of thickening of crust with an average continental geotherm. A companion paper discusses these results in the context of attempts to use metamorphic petrology data to give information on tectonic processes.

The comma, quote format should work.
Is debug turned off for phpBB?
Are you using the correct field numbers? The first field is field 0. So ... the username field should be 0, the password field is 1 and the email field is 2.
